TIDE AND WAVE MOTOR.

SPECIFICATION forming part of Letters Patent No. 7 7 5,421, datedNovember 22, 1904,

Application filed April 21, 1903. Serial No. 153,667. (No model Be itknown that I, GEORGE WV. HAzEL, residing' at Aurora, in the county ofKane and State of Illinois, have invented certain useful Improvements inTide and Wave Motors; and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to a new and novel improvementin tide and wavemotors.

rlhe aim of my invention is to provide a mechanism to use, utilize, andconvert into force the power of waves and the movement of afloating bodyin water, to utilize the rise and fall of that body in response to thewave or water action upon said body.

By means of my invention I am enabled to utilize the power of waves, thetides, and swells and convert the same into motive force.

In the accompanying drawings I have shown in'Figure l a mechanism bymeans of which I utilize waves and tides to compress air, while Fig. 2shows a top view of Fig. l.

As has been set forth, the aim of my invention is to provide a means toutilize the power of waves, swells, and tides. This I accomplish inproviding a base 1, as shown in Fig. 1, preferably of masonry, fromwhich base extends upward a suitable distance a plurality of piers l, 2,and 3. Held between these piers is a vessel A, preferably circular, asshown in Figs. l and 2, which vessel is permitted an upand-down movementwithin the confines of thezpiers l, 2, and 3, and this up-and-downmovement of this vessel A in response to the action of the tide, swells,or waves is utilized in compressing air, which is stored within asuitable receiver.

In fulfilling' the aim of my invention I provide the base l with asuitable anchor-plate 5, having an ear 6, and from this ear 6 extends aconnecting-rod 7.

The housing A, held between the piers 1, 2., and 3, embodies a lowerair-chamber D, provided with one or more cylinders, as l0,

within which reciprocates a suitable piston 9, provided with an ear l0,secured to the connecting-rod 7. This cylinder l() extends upward asuitable distance and above is provided with a suitable intake-valve Il,while extending from this cylinder'lO is a supply-pipe l2, provided witha check-valve I3 of any suitable construction. This supply-pipe 12enters the receiver or air-chamber D, as is disclosed in Fig. l. Abovethe air chamber or receiver D is provided a deck or housing B, adaptedto contain the machinery and provide quarters for the attendants incharge of this apparatus. Now these instrumentalities are so constructedand arranged that when the tide is at its highest level the vessel willof course be at its highest position, in which condition the piston 9will be at its lowermost position with the cylinder lO. Now as the tiderecedes the vessel sinks, so that the air within the cylinder 10 iscompressed, finding an escape through the valve-provided pipe l2 andbeing stored within the receiver I). As the vessel rises in obedience tothe action of the tide the piston, being' stationary, of course, tinallycomes within the lower portion of the cylinder 10, the compressed airbeing prevented from escaping by means of a checkvalve 13, while theintake-valve l1 permits a free entry of air, and as soon as the tiderecedes the air is again compressed. However, the action of the wavesand swells is also utilized, and at every upward movement of the vesselair is taken in, and at every downward movement of the vessel air iscompressed. Now in order to utilize the upward movement of the vessel Iprovide the cylinder 10 with a head 42, through which the connecting-rod7 extends, and provide the check-valve 40, leading into the receiver orair-chamber D. As this head l2 is below the water-line, I extend fromthe same a suitable tube 43,-whicl1 is led upward a suitable distanceand above is provided with a check-valve 4I, so that at every up or downmovement the air is compressed upon one side or the other, the airalways being taken in on the side opposite the one in which thecompression is taking place.

Having thus described my said invention,

what I clairn as new, and desire to secure by United States LettersPatent, is-

In a device of the character described, the combination with a pluralityof partially-submerged piers, of a buoyant housing confined by saidpiers, an air-receiver within said housing, a cylinder verticallypositioned within said housing, a valve within the lower end of saidcylinder, a valve within the upper end of said cylinder, a piston withinsaid cylinder, a rod extending from said piston and being suit-
